It is recommended that audio is handled via audio broadcast through the instructor's workstation, and that students mute the audio on their own computers. The benefit of this setup is that students can each log in to the WebEx session and therefore have access to the chat panel to type questions at any time. This also allows students to follow along in another window if they would like to get hands-on practice during the session.
